Exercise 12

As described in Figure 7.10, host DNA is hydrolyzed into small pieces, which are occasionally assembled with phage proteins, creating a phage with bacterial chromosomal DNA. If the breakage of the chromosomal DNA is not random (i.e., it is more likely to break at certain spots as opposed to other spots), how might nonrandom breakage affect cotransduction frequency
FIGURE 7.10 Transduction in bacteria. Genes Traits During transduction, a phage carries a segment of bacterial DNA from a donor to a recipient cell. In this case, the phage carried a segment of DNA with the his + gene and transferred this gene to a recipient cell that was originally his (unable to synthesize histidine). Following transduction, the recipient cell became his + , so it now can synthesize histidine.
